The Krychów site is, to a considerable extent, a former water reservoir, currently overgrown with peatland vegetation. The fen mire surrounding the former reservoir is intensively drained and completely overgrown with mire vegetation consisting mainly of the Caricetum lasiocarpae sedge complex. Willows and reed are very expansive in the fen, especially at its edges. In the scrub locally, shrubby birch Betula humilis has a very high proportion, and locally co-dominates. With the exception of the intact peatland in its central part, the area is covered with meadow vegetation and, with herbaceous vegetation on unmown fragments. The meadows adjoining the peatland are Molinia meadows dominated by Molinia caerulea, locally overgrown with blackberry and raspberry Rubus spp., sand reed Calamagrostis epigejos and other species alien to the habitat. In the peatland part of the area, shrubby species such as willows and birches occur in the meadow fragments. Nowadays, they are regularly mown, however regrow from the remaining roots and trunks. The south-western part is mainly poor meadow communities (Molinio-Arrhenatheretea and Arrhenatheretalia) on mineral soil or mineralised peat. With the exception of the intact peatland, the site is used for haymaking. The site belongs to private owners, with whom the OTOP BirdLife Poland has signed relevant agreements allowing the re-wetting works to be carried out.
